Which Cloud Service Provider Has the Largest Market Share?
Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP) are the cloud service providers with the largest market share, collectively capturing over 65% of spending on cloud infrastructure services. Below is a summary table of the top 10 cloud service providers by market share, highlighting AWS’ 31% market share, Microsoft Azure’s 24% market share, and Google Cloud’s 11.5% market share.

# Cloud Service Provider Market Share
1 Amazon Web Services (AWS) 31%
2 Microsoft Azure 24%
3 Google Cloud Platform (GCP) 11.5%
4 Alibaba Cloud 4%
5 Oracle Cloud 3%
6 IBM Cloud 2.5%
7 Tencent Cloud 2%
8 OVHcloud <1%
9 DigitalOcean <1%
10 Linode (Akamai) <1%

Over the past 5 years, AWS has maintained its market share in the low-30% range, Microsoft Azure has been an aggressive market share gainer, rising from approximately 10% historically, while Google Cloud has been steadily increasing its market share from its prior base of 5%. With market share gainers, there are also corresponding market share losers over this time period, which include IBM Cloud and a number of small cloud service providers.

Who are the Small Cloud Service Providers?
While the top 10 cloud service providers capture approximately 78% of spending on cloud infrastructure services, there is still a significant number of small vendors present in global markets. For example, these cloud service providers include those targeting a certain niche, such as small- and medium-sized businesses (SMBs) or ones that operate regionally, such as in Europe or Asia Pacific. Below are examples of these small cloud service providers:

China: Baidu AI Cloud, Huawei Cloud, Kingsoft Cloud, JD Cloud, QingCloud, UCloud
Europe: Bleu (Orange and Capgemini), Hetzner, Leaseweb
Japan and Korea: Fujitsu, NTT, SoftBank, NAVER Cloud, KT Cloud
Private Cloud / Managed Services: Hewlett Packard Enterprise (HPE), Rackspace, VMware
SaaS Partners: Salesforce, SAP
SMBs: Heroku, UpCloud, Vultr
Within the cloud service provider market, there is an important distinction to make for managed services providers like Rackspace. Managed services providers help enterprises migrate, architect, and deploy workloads to the public cloud. Subsequently, these managed services providers ‘manage’ the IT infrastructure for their customers across multiple environments, including public cloud, private cloud, and on-premises. Through this business model, the cloud service providers still remain as the ultimate owners and providers of IT infrastructure.

What are Cloud Service Providers?
Cloud service providers offer on-demand infrastructure and tools for developers, start-ups, small- and medium-sized businesses, and large enterprises to build, deploy, and scale their software applications and databases. The two main service models which cloud service providers operate in are known as Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS), which are comprised of the following:

Infrastructure-as-a-Service (IaaS): compute, storage, and networking
Platform-as-a-Service (PaaS): database management systems and application platforms
With this combined IaaS and PaaS infrastructure, cloud service providers enable a wide range of use cases, including web & mobile applications, website hosting, e-commerce, media & gaming, managed services, among many more. These computing and storage services rely on shared servers which offer a high degree of scalability and continuity. Typically, customers consume cloud computing services on a pay-per-use basis.

Additionally, certain public cloud service providers offer Software-as-a-Service (SaaS), which refers to end user applications.

Regions and Availability Zones Explained
Cloud service providers build their digital infrastructure around what are known as regions and availability zones. A region is a physical location in the world where a cloud service provider has multiple availability zones. These availability zones consist of one or more isolated data centers, that are housed in separate buildings, each with redundant power, cooling, networking, and fiber-optic connectivity.

Regions and Availability Zones – Example
Microsoft Azure Regions and Availability Zones

Availability zones enable end users to operate production applications and databases that are more highly available, fault tolerant, and scalable than is possible from an individual data center.

Virtualization – A Key Advantage of the Cloud
Cloud service providers differentiate themselves from the capabilities of individual servers and data centers through virtualization, which means adding an abstraction layer between hardware and applications. In turn, virtualization enables multiple workloads and operating systems to run on the same physical server. As such, virtualization facilitates the critical competitive advantages of the cloud, including scalability, maximizing resource utilization, and provisioning more workloads with lower operating expenses.

What are the 5 Benefits of Cloud Computing?
The 5 benefits of cloud computing are scalability, pay-per-use, speed & agility, outsourcing, and global reach:

Scalability: an enterprise’s internal IT systems may not be scalable to meet peak demand for workloads, unless they maintain excess capacity – which is costly. By using cloud computing, customers can instantly increase or decrease their hardware and software capacity needs to meet business requirements
Pay-Per-Use: instead of investing capital expenditures (CapEx) in data centers and servers prior to knowing how they are going to be used, customers can pay only when they consume computing resources, and pay only for how much they consume
Speed and Agility: new IT resources can be provisioned in a cloud computing environment with only a few clicks. Therefore, customers can reduce the time to make those resources available to developers from weeks to just minutes
Outsourcing: cloud computing enables customers to avoid racking, stacking, and powering servers, in addition to eschewing the ongoing maintenance of their data centers
Global Reach: applications can be deployed in multiple regions around the world with just a few clicks. In turn, this enables applications to have lower latency and provides a better experience for end users
At the same time, a significant number of enterprises are shifting to hybrid and multi-cloud environments to avoid vendor lock-in and to preserve the flexibility to host sensitive workloads in a more secure environment. Below are definitions of hybrid cloud and multi-cloud:

Hybrid Cloud: application deployments in a combination of different environments including on-premises, private cloud, and public cloud
Multi-Cloud: application deployments with several public cloud service providers, instead of only using a single public cloud service provider
Which Cloud Service Provider is Cheapest?
To answer the questions: Which is cheapest cloud provider? and How much do cloud computing services cost?, Dgtl Infra reviewed a recent comparison by Linode, which studied the cost per month of a CPU Dedicated/Optimized 2vCPU, 4GB RAM, 80GB SSD deployment. Below is a summary of the monthly costs for this deployment from the four largest public cloud service providers, namely Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), and Alibaba Cloud:

# Cloud Service Provider Cost per Month % Higher
1 Alibaba Cloud $48.42 —
2 Google Cloud Platform (GCP) $63.38 31%
3 Microsoft Azure $70.05 45%
4 Amazon Web Services (AWS) $71.47 48%
As shown in the example above, for the CPU Dedicated/Optimized 2vCPU, 4GB RAM, 80GB SSD deployment, Alibaba Cloud was the cheapest public cloud service provider at $48.42 per month. In contrast, Amazon Web Services (AWS) was the most expensive public cloud service provider, at a cost of $71.47 per month, 48% higher than Alibaba Cloud.

Although the above analysis highlights the cheapest public cloud service provider among the large vendors, in reality the smaller cloud service providers, such as OVHcloud, DigitalOcean, and Linode are the most cost-effective.
